Side-by-Side Specs
| Spec | BYD SEAL U | Hyundai IONIQ 5 N |
|---|---|---|
| Compared variant | 87 kWh Design | N Performance |
| Battery (approx.) | ~87 kWh | ~80 kWh |
| WLTP range (rated) | ~500 km | ~448 km |
| Efficiency (approx.) | ~205 Wh/km | ~205 Wh/km |
| DC fast charging (published) | up to 140 kW | up to 350 kW |
| 10-80% charge time (approx.) | ~34 min | ~18 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Hyundai IONIQ 5 N has the higher published DC fast-charging figure at 350 kW, which is roughly 150% higher than the BYD SEAL U at 140 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.
For the 10-80% charge (the most common DC fast charging scenario), the Hyundai IONIQ 5 N finishes in about 18 minutes, which is 16 minutes quicker than the BYD SEAL U at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BYD SEAL U has a WLTP rated range of approximately 500 km, which is roughly 52 km more than the Hyundai IONIQ 5 N at approximately 448 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.
Efficiency matters more than battery size for daily driving costs. The Hyundai IONIQ 5 N consumes 205 Wh/km, compared to 205 Wh/km for the BYD SEAL U. That means the Hyundai IONIQ 5 N uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.
A more efficient car does not always mean more range. Battery size plays a role too. The BYD SEAL U has approximately 87 kWh of useable battery , while the Hyundai IONIQ 5 N has approximately 80 kWh.
Which One Should You Choose?
If fast charging is your priority, the Hyundai IONIQ 5 N has the higher published DC figure (up to 350 kW) while matching the quickest published 10-80% time at approximately 18 minutes. For long road trips, published stop time matters more than the headline kW number alone.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
Both cars have similar efficiency at 205 Wh/km, so daily charging costs should be comparable.
For maximum range between charges, the BYD SEAL U has a WLTP rated range of approximately 500 km, which is roughly 52 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
